What this server can do

52 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.

add_text_overlay(name, text, projectId, layerIndex, startSeconds, idempotencyKey, durationSeconds, expectedRevision)

Add an editable text overlay to a project timeline at an exact time and layer. Required: projectId, text, idempotencyKey.

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
